Abstract
An adapter for collecting signaling, input in a telephone exchange by division of space and common control, including terminal equipment for voice signals that transmit the mic connections in the form of time-coded pulses multiplexed. Each terminal equipment demultiplexes and decodes the information applied to the central, through the mic connections, so that it is possible in the central, to switch the restored analog voice signals, and to simultaneously provide, on the one hand, in parallel, the bits of the sample sent by each frame from the signaling channel of the mic link that receives it, and on the other hand, the frame signal of those bits transmitted in parallel. This frame signal is obtained from the clock of the remote exchange to which the mic connection is connected. This adapter being characterized because it comprises: - detection elements, connected to the clock of the local exchange to provide a periodic detection signal whose period is shorter than half the duration of the frame signal; -elements for initiating the temporary storage of the signaling sample provided with a frame signal when a second detection signal occurs within this frame signal, and - writing inhibition elements triggered by the end of the second detection signal to inhibit any writing for the remainder of the duration of the considered frame signal.
